But headteacher Chris Edwards says the school has “very clear rules” on appearance and the “vast majority” of parents make sure their children abide by them.

The Year 8 pupil was pulled out of class on Friday morning by her head of year as a result of her new dip dye hair style.

Mrs Halford said: “I’ve made the decision to pull her out of the school until it’s gone.

“It’s not affecting her learning having pink hair but they’ve told me her absence will now be put down as unauthorised.

“I think it’s bullying – they are saying their pupils can’t have individuality.

“The dye is one of those wash out ones, so we are of course going to keep washing it, but it will take a few weeks.”

Isolation consists of the pupil being put in a room alone, restricting them from mixing with any other pupils.

Mrs Halford added: “She is a model pupil aside from this – there have been no problems with behaviour or learning.

“Other girls go in with a full face of make-up or their skirts hitched up to their thighs.

“They’re allowed to have mobile phones on them.

“I just don’t understand why this is such an offence.

“I just don’t see how this could possibly affect her, or anyone else’s, learning.

“She’s lucky this isn’t a particularly important year, otherwise implementing this kind of punishment for something so menial would have far greater consequences.

“I’m going to get a private tutor so she can keep up with her lessons.”

Mrs Edwards said: “At Ringwood School we have very clear rules with regard to appearance and uniform which parents agree to when send their child to the school.

“Our rules state that hair should be traditionally styled – extremes of fashion eg shaved hair, beads, braids, unnatural tints, dyes and highlights are not acceptable in school.

“If a student arrives at school with inappropriate uniform or appearance arrangements are made to continue with learning in isolation while contact is made with parents to arrange to resolve the problem.

“I am very grateful to the vast majority of our parents who are very supportive of the high standards we expect from all of our young people.”

When / if this girl enters her adult working life she will again come across rules of appearance - - suit, uniform or safety gear. Best to get used to it now unless she intends living off the state.
